A misfiring engine will cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. Typically an engine misfire under load, will be a problem with the ignition system, while low engine speed problems will be a vacuum, fuel management or compression issue.
Coral colonies grow through a form of asexual reproduction known as budding, in which polyps divide themselves to form new polyps . Corals can also reproduce sexually by spawning, which in Platygyra daedalea involves the release of gametes into the water, for external fertilisation. Platygyra daedalea is hermaphroditic, meaning that each polyp produces both eggs and sperm.
By night the polyps feed on plankton by capturing it with their tentacles. If the rate of photosynthetic production is too high, corals have the ability to control the amount of zooxanthellae in their tissues by expelling it; this is known as coral bleaching, which is normal.
